This application claims the benefit of Provisional application Ser. No.60/125,043, filed Mar. 18, 1999.

FIELD OF THE INVENTION

The present invention relates to stable aqueous perfumed householdcleaning and deodorizing compositions containing a surfactant and aperfume. The perfume is in a solubilized or emulsified state andcontains a substantial proportion of hydrophobic perfume materials inorder to impart a clean, desirable, scent to substrates upon which theproduct is used. The composition is packaged in a polyethylene bottlewherein the interior of the bottle has been modified in order to preventundesirable changes in the perfume caused by absorption and/ortransmission of the hydrophobic components into and/or through thepolyethylene during storage.

BACKGROUND

It is recognized that consumers appreciate household cleaning, fabrictreatment and deodorizing products which impart a pleasant odor tosurfaces treated with said products. It has been found that in theformulation of perfumes for said products, the use of a substantialproportion of hydrophobic perfume materials in said perfumes isdesirable.

For convenience and flexibility in use, it is highly desirable thathousehold cleaning and deodorizing and fabric treatment compositions bein liquid form and packaged in plastic bottles. For cost reasons,polyethylene is a preferred material for manufacturing bottles for suchcompositions. It has been found however, that hydrophobic perfumematerials have a tendency to be lost from the liquid product byabsorption into and/or transmission through the polyethylene duringstorage of the composition. This results in a change in the odorcharacter of the composition and a reduction in the fragrance benefitwhich would otherwise be obtained on surfaces treated with thecomposition.

All documents referred to herein are incorporated by reference and allpercentages and proportions are by weight, unless otherwise specified.

SUMMARY OF THE INVENTION

The present invention relates to a bottled aqueous household cleaning,fabric treatment or deodorizing product comprising, in addition towater, from 0.01% to 50% of a surfactant and from 0.003% to 5% of aperfume wherein the perfume contains at least 10% of one or morehydrophobic perfume ingredients having a ClogP of greater than 3, andwherein the said product is present in a high density polyethylenebottle and wherein the bottle has a continuous inner surface layer of amaterial selected from the group consisting of:

a) nylon

b) polyethylene terephthalate and

c) fluorinated high density polyethylene

DETAILED DESCRIPTION OF THE INVENTION

In accordance with the present invention it has been found that whenaqueous household cleaning, fabric treatment or deodorizing compositionscomprising water, surfactant and perfume are packaged in conventionalhigh density polyethylene (HDPE) bottles there is a tendency for certainhydrophobic perfume ingredients (i.e. those having a ClogP of about 3 orgreater) to be lost from the perfume. This is apparently by migrationinto and/or through the polyethylene bottle material. When the perfumescontain substantial amounts of such perfume ingredients, such lossconsiderably alters the intended fragrance character of the perfume.Bottles made of polyethylene terephthalate (PET) or glass do not exhibitthis detrimental effect on perfumes. However, consumers prefer plasticcontainers over glass, and polyethylene is a less expensive plastic thanPET. It has now been found that by use of HDPE bottles which havecertain interior surface modifications, the loss of these hydrophobicperfume ingredients can be substantially eliminated.

The present invention is a bottled aqueous household cleaning, fabrictreatment or deodorizing composition comprising, in addition to water,from 0.01% to 50% of a surfactant and from 0.003% to 5% of a perfumewherein the perfume contains at least 10% of one or more hydrophobicperfume ingredients having a ClogP of greater than 3, and wherein thesaid composition is present in a high density polyethylene bottlewherein the bottle has a continuous inner surface layer of a materialselected from the group consisting of:

a) nylon

b) polyethylene terephthalate and

c) fluorinated high density polyethylene

A. Surfactants

Surfactants suitable for use in the compositions of the presentinvention can be any of those suitable for use in household cleaning,fabric treatment or deodorizing compositions. These include anionic,nonionic, cationic, ampholytic and zwitterionic detergents.

Examples of anionic detergents include C₈-C₂₂ alkyl sulfates,alkylbenzene sulfonates having from 9 to 15 carbon atoms in the alkylgroup, alkyl ethyleneoxide ether sulfates having from 8-22 carbon atomsin the alkyl chain and from 1 to 30 ethylene oxide groups, and C₈ to C₂₂fatty acid soaps. Examples of nonionic surfactants include condensatesof from 3 to 30 moles of ethylene oxide with an aliphatic alcohol of 8to 22 carbon atoms, condensates of 5 to 30 moles of ethylene oxide withan alkyl phenol wherein the alkyl contains 9 to 15 carbon atoms, and C₈to C₂₂ alkyl dimethyl amine oxides. Examples of ampholytic andzwitterionic surfactants are found in U.S. Pat. No. 3,929,678, Laughlinet al, issued Dec. 30, 1975 at Col, 19, line 38 through Col. 22 line 48.Examples of cationic surfactants are tetraalkyl quaternary ammoniumsalts having at least one alkyl chain of 8 to 22 carbon atoms, whereinthe other alkyl groups can contain from 1 to 22 carbon atoms and whereinthe anionic counterion is halogen, ethylsulfate or methylsulfate. Theterm “household cleaning and fabric treatment and deodorizingcompositions” herein includes fabric laundering, softening andfreshening compositions, and floor, rug and other household surfacetreatment compositions where it is desired to clean and/or impart abeneficial treatment or property to the surface. Surtactants are used atlevels of from 0.01% to 50%, depending on the intended usage of theproduct. Typical levels are from 0.1% to 30% and 5% to 20%

Additional surfactants are disclosed in U.S. Pat. No. 3,664,961, Norris,issued May 23, 1972.

B. Perfumes

The compositions of the present invention contain perfumes at levels offrom 0.003% to 5%, preferably from 0.003% to 1% and more preferably from0.05% to 0.2%. The perfumes contain a substantial portion of perfumeingredients (at least about 10%, preferably at least 50%, morepreferably at least 70%) which have a ClogP of at least 3.

The logP of many perfume ingredients has been reported; for example, thePomona92 database, available from Daylight Chemical Information Systems,Inc. (Daylight CIS), Irvine, Calif., contains many, along with citationsto the original literature. However, the logP values are mostconveniently calculated by the Pamona Med Chem/Daylight “CLOGP” program,Version 4.42 available from Biobyte Corporation, Claremont, Calif. Thisprogram also lists experimental logP values when they are available inthe Pomona92 database. The “calculated logP” (ClogP) is determined bythe fragment approach of Hansch and Leo (cf., A. Leo, in ComprehensiveMedicinal Chemistry, Vol. 4, C. Hansch, P. G. Sammens, J. B. Taylor andC. A. Ramsden, Eds., p. 295, Pergamon Press, 1990, incorporated hereinby reference). The fragment approach is based on the chemical structureof each perfume ingredient, and takes into account the numbers and typesof atoms, the atom connectivity, and chemical bonding. The ClogP values,which are the most reliable and widely used estimates for thisphysicochemical property, are preferably used instead of theexperimental logP values in the selection of perfume ingredients whichare useful in the present invention.

The following table contains a listing of examples of perfumeingredients having a ClogP of at least 3 which are useful in the presentinvention.

Preferred compositions herein which have an especially good deodorizingeffect on surfaces (e.g. fabrics, carpets, counter tops, etc.) treatedwith the composition, contain cyclodextrin. In addition to the perfumein the composition providing the desired odor, to the treated surface.Cyclodextrin has the ability to absorb odors such as present inperspiration, urine, etc. present on the treated surface.

Preferably, the cyclodextrins used in the present invention are highlywater-soluble such as, alpha-cyclodextrin and/or derivatives thereof,gamma-cyclodextrin and/or derivatives thereof, derivatisedbeta-cyclodextrins, and/or mixtures thereof. The derivatives ofcyclodextrin consist mainly of molecules wherein some of the OH groupsare converted to OR groups. Cyclodextrin derivatives include, e.g.,those with short chain alkyl groups such as methylated cyclodextrins,and ethylated cyclodextrins, wherein R is a methyl or an ethyl group;those with hydroxyalkyl substituted groups, such as hydroxypropylcyclodextrins and/or hydroxyethyl cyclodextrins, wherein R is a—CH₂—CH(OH)—CH₃ or a —CH₂CH₂—OH group; branched cyclodextrins such asmaltose-bonded cyclodextrins; cationic cyclodextrins such as thosecontaining 2-hydroxy-3-(dimethylamino)propyl ether, wherein R isCH₂—CH(OH)—CH₂—N(CH₃)₂ which is cationic at low pH; quaternary ammonium,e.g., 2-hydroxy-3-(trimethylammonio)propyl ether chloride groups,wherein R is CH₂—CH(OH)—CH₂—N⁺(CH₃)₃Cl⁻; anionic cyclodextrins such ascarboxymethyl cyclodextrins, cyclodextrin sulfates, and cyclodextrinsuccinylates; amphoteric cyclodextrins such as carboxymethyl/quaternaryammonium cyclodextrins; cyclodextrins wherein at least one glucopyranoseunit has a 3-6-anhydro-cyclomalto structure, e.g., themono-3-6-anhydrocyclodextrins, as disclosed in “Optimal Performanceswith Minimal Chemical Modification of Cyclodextrins”, F. Diedaini-Pilardand B. Perly, The 7th International Cyclodextrin Symposium Abstracts,April 1994, p. 49, said references being incorporated herein byreference; and mixtures thereof.

Highly water-soluble cyclodextrins are those having water solubility ofat least about 10 g in 100 ml of water at room temperature, preferablyat least about 20 g in 100 ml of water, more preferably at least about25 g in 100 ml of water at room temperature. The availability ofsolubilized, uncomplexed cyclodextrins is essential for effective andefficient odor control performance. Solubilized, water-solublecyclodextrin can exhibit more efficient odor control performance thannon-water-soluble cyclodextrin when deposited onto surfaces, especiallyfabric.

Examples of preferred water-soluble cyclodextrin derivatives suitablefor use herein are hydroxypropyl alpha-cyclodextrin, methylatedalpha-cyclodextrin, methylated beta-cyclodextrin, hydroxyethylbeta-cyclodextrin, and hydroxypropyl beta-cyclodextrin. Hydroxyalkylcyclodextrin derivatives preferably have a degree of substitution offrom about 1 to about 14, more preferably from about 1.5 to about 7,wherein the total number of OR groups per cyclodextrin is defined as thedegree of substitution. Methylated cyclodextrin derivatives typicallyhave a degree of substitution of from about 1 to about 18, preferablyfrom about 3 to about 16. A known methylated beta-cyclodextrin isheptakis-2,6-di-O-methyl-β-cyclodextrin, commonly known as DIMEB, inwhich each glucose unit has about 2 methyl groups with a degree ofsubstitution of about 14. A preferred, more commercially available,methylated beta-cyclodextrin is a randomly methylated beta-cyclodextrin,commonly known as RAMEB, having different degrees of substitution,normally of about 12.6. RAMEB is more preferred than DIMEB, since DIMEBaffects the surface activity of the preferred surfactants more thanRAMEB. The preferred cyclodextrins are available, e.g., from CerestarUSA, Inc. and Wacker Chemicals (USA), Inc.

It is also preferable to use a mixture of cyclodextrins. The amount ofcyclodextrins used in the compositions will range from 0.01% to about20%. If the composition is intended to be diluted before use it willcontain from 3% to 20%, preferably 5% to 10%. Compositions intended tobe used in undiluted form will generally contain from 0.01% to 5%,preferably 0.1% to 3%, more preferably 0.5% to 2%.

When formulating compositions with cyclodextrins, it is desirable to usesurfactants which have especially good compatibility with cyclodextrin.Suitable cyclodextrin-compatible surfactants can be readily identifiedby the absence of effect of cyclodextrin on the surface tension providedby the surfactant. This is achieved by determining the surface tension(in dyne/cm²) of aqueous solutions of the surfactant in the presence andin the absence of about 1% of a specific cyclodextrin in the solutions.The aqueous solutions contain surfactant at concentrations ofapproximately 0.5%, 0.1%, 0.01%, and 0.005%. The cyclodextrin can affectthe surface activity of a surfactant by elevating the surface tension ofthe surfactant solution. If the surface tension at a given concentrationin water differs by more than about 10% from the surface tension of thesame surfactant in the 1% solution of the cyclodextrin, that is anindication of a strong interaction between the surfactant and thecyclodextrin. The preferred surfactants herein should have a surfacetension in an aqueous solution that is different (lower) by less thanabout 10%, preferably less than about 5%, and more preferably less thanabout 1% from that of the same concentration solution containing 1%cyclodextrin.

(a) Block Copolymers

Nonlimiting examples of cyclodextrin-compatible nonionic surfactantsinclude block copolymers of ethylene oxide and propylene oxide. Suitableblock polyoxyethylene-polyoxypropylene polymeric surfactants, that arecompatible with most cyclodextrins, include those based on ethyleneglycol, propylene glycol, glycerol, trimethylolpropane andethylenediamine as the initial reactive hydrogen compound. Polymericcompounds made from a sequential ethoxylation and propoxylation ofinitial compounds with a single reactive hydrogen atom, such as C₁₂₋₁₈aliphatic alcohols, are not generally compatible with the cyclodextrin.Certain of the block polymer surfactant compounds designated Pluronic®and Tetronic® by the BASF-Wyandotte Corp., Wyandotte, Mich., are readilyavailable.

Nonlimiting examples of cyclodextrin-compatible surfactants of this typeinclude:

Pluronic Surfactants with the general formulaH(EO)_(n)(PO)_(m)(EO)_(n)H, wherein EO is an ethylene oxide group, PO isa propylene oxide group, and n and m are numbers that indicate theaverage number of the groups in the surfactants.

(b) Siloxane Surfactants

A preferred class of cyclodextrin-compatible nonionic surfactants arethe polyalkyleneoxide polysiloxanes having a dimethyl polysiloxanehydrophobic moiety and one or more hydrophilic polyalkylene side chainsand have the general formula:

R¹—CH₃)₂SiO—[(CH₃)₂SiO]_(a)—[(CH₃)(R¹)SiO]_(b)—Si(CH₃)₂—R¹

wherein a+b are from about 1 to about 50, preferably from about 3 toabout 30 , more preferably from about 10 to about 25, and each R¹ is thesame or different and is selected from the group consisting of methyland a poly(ethyleneoxide/propyleneoxide) copolymer group having thegeneral formula:

—(CH₂)_(n)O(C₂H₄O)_(c)(C₃H₆O)_(d)R²

with at least one R¹ being a poly(ethyleneoxide/propyleneoxide)copolymer group, and wherein n is 3 or 4, preferably 3; total c (for allpolyalkyleneoxy side groups) has a value of from 1 to about 100,preferably from about 6 to about 100; total d is from 0 to about 14,preferably from 0 to about 3; and more preferably d is 0; total c+d hasa value of from about 5 to about 150, preferably from about 9 to about100 and each R² is the same or different and is selected from the groupconsisting of hydrogen, an alkyl having 1 to 4 carbon atoms, and anacetyl group, preferably hydrogen and methyl group.

Examples of this type of surfactants are the Silwet® surfactants whichare available OSi Specialties, Inc., Danbury, Conn. RepresentativeSilwet surfactants are as follows.

Name Average MW Average a + b Average total c L-7608 600 1 9 L-76071,000 2 17 L-77 600 1 9 L-7605 6,000 20 99 L-7604 4,000 21 53 L-76004,000 11 68 L-7657 5,000 20 76 L-7602 3,000 20 29

The molecular weight of the polyalkyleneoxy group (R¹) is less than orequal to about 10,000. Preferably, the molecular weight of thepolyalkyleneoxy group is less than or equal to about 8,000, and mostpreferably ranges from about 300 to about 5,000. Thus, the values of cand d can be those numbers which provide molecular weights within theseranges. However, the number of ethyleneoxy units (—C₂H₄O) in thepolyether chain (R¹) must be sufficient to render the polyalkyleneoxidepolysiloxane water dispersible or water soluble. If propyleneoxy groupsare present in the polyalkylenoxy chain, they can be distributedrandomly in the chain or exist as blocks. Preferred Silwet surfactantsare L-7600, L-7602, L-7604, L-7605, L-7657, and mixtures thereof.Besides surface activity, polyalkyleneoxide polysiloxane surfactants canalso provide other benefits, such as antistatic benefits, lubricity andsoftness to fabrics.

The preparation of polyalkyleneoxide polysiloxanes is well known in theart. Polyalkyleneoxide polysiloxanes of the present invention can beprepared according to the procedure set forth in U.S. Pat. No.3,299,112, incorporated herein by reference. Typically,polyalkyleneoxide polysiloxanes of the surfactant blend of the presentinvention are readily prepared by an addition reaction between ahydrosiloxane (i.e., a siloxane containing silicon-bonded hydrogen) andan alkenyl ether (e.g., a vinyl, allyl, or methallyl ether) of an alkoxyor hydroxy end-blocked polyalkylene oxide). The reaction conditionsemployed in addition reactions of this type are well known in the artand in general involve heating the reactants (e.g., at a temperature offrom about 85° C. to 110° C.) in the presence of a platinum catalyst(e.g., chloroplatinic acid) and a solvent (e.g., toluene).

(c) Anionic Surfactants

Nonlimiting examples of cyclodextrin-compatible anionic surfactants arethe alkyldiphenyl oxide disulfonate, having the general formula:

wherein R is an alkyl group. Examples of this type of surfactants areavailable from the Dow Chemical Company under the trade name Dowfax®wherein R is a linear or branched C₆-C₁₆ alkyl group. An example ofthese cyclodextrin-compatible anionic surfactant is Dowfax 3B2 with Rbeing approximately a linear C₁₀ group. These anionic surfactants arepreferably not used when the antimicrobial active or preservative, etc.,is cationic to minimize the interaction with the cationic actives, sincethe effect of both surfactant and active are diminished.

The surfactants above are either weakly interactive with cyclodextrin(less than 5% elevation in surface tension, or non-interactive (lessthan 1% elevation in surface tension). Normal surfactants like sodiumdodecyl sulfate and dodecanolpoly(6)ethoxylate are strongly interactive,with more than a 10% elevation in surface tension in the presence of atypical cyclodextrin like hydroxypropyl beta-cyclodextrin and methylatedbeta-cyclodextrin.

Typical levels of cyclodextrin-compatible surfactants in usagecompositions are from about 0.01% to about 2%, preferably from about0.03% to about 0.6%, more preferably from about 0.05% to about 0.3%, byweight of the composition. Typical levels of cyclodextrin-compatiblesurfactants in concentrated compositions are from about 0.1% to about8%, preferably from about 0.2% to about 4%, more preferably from about0.3% to about 3%, by weight of the concentrated composition.

Deodorizing compositions containing cyclodextrin are more fullydescribed in pending Provisional Application No. 60/109834, filed Nov.25, 1998. HDPE Bottles.

(d) High Density Polyethylene Bottles.

The modified HDPE bottles used in the present invention are modified byhaving, as their interior surface, a material selected from nylon,polyethylene terephthalate or fluorinated polyethylene, which acts as abarrier to prevent absorption into and/or transmission through the HDPE.

HDPE bottles of this type are known to the art. HDPE bottles with anylon or PET inner layer can be made by the blow molding process whereinconcentric layers of heat softened HDPE, an adhesive, and nylon or PETare formed into a parison and coextruded as a hollow tube into a moldcavity and forced by pressurized air against the walls of the cold moldcavity to form the bottle. The bottle solidifies by cooling to form anHDPE bottle which has an inner surface of nylon or PET.

HDPE bottles having an inner surface of fluorinated HDPE can be made byknown methods whereby the inner surface of heated, preformed HDPEbottles are subjected to contact with fluorine gas. The fluorine reactswith the polyethylene to form a layer of fluorinated polyethylene. SeeSurface Treatment Improves Polyethylene Barrier Protection PackageEngineering, November, 1981 p.64. Also U.S. Pat. No. 4,081,574, issuedMar. 28, 1964 and U.S. Pat. No. 3,998,180, issued Dec. 21, 1976.

The inner layer of nylon, PET or fluorinated polyethylene should becontinuous and have a thickness of at least about 0.0005 in.

The following examples are presented for illustrative purposes, and arenot intended to, in any way, limit the scope of the invention.

EXAMPLE I

In this example the following deodorizing composition for inanimatesurfaces (e.g. rugs, clothing, counter tops, etc.) containing a perfume,wherein the perfume consisted of approximately 75% ingredients having aClogP greater than 3 and about 25% ingredients having a ClogP less than3,was evaluated in HDPE bottles for perfume ingredient loss.

The compositions were stored in HDPE bottles for 8 weeks at ambienttemperature. After store, gas chromatography analysis was used todetermine the amount of the various perfume ingredients remaining in thecomposition and approximate loss was calculated, based on the amount ofeach ingredient originally present.

This test demonstrates that perfume ingredients of ClogP greater than 3undergo significant loss when stored in HDPE bottles.

EXAMPLE II

In this example a composition of the same base formula as above,containing 0.065% of the same perfume was placed in several bottlevariations and stored at 70° F. and 120° F., respectively.

It had been previously observed that perfume ingredients with ClogPabove 3 tend to cause this composition to be cloudy, thus an increase inlight transmittance can be used to indicate loss of these ingredientsfrom the composition.

The % light transmittance of product stored in the various bottles isshown below.
